Observational studies have reported a relationship between multiple common dermatoses and mental illness. To assess the potential bidirectional causality between 3 skin disorders (psoriasis, eczema, and urticaria) and 4 psychiatric disorders (bipolar disorder, schizophrenia, major depressive disorder, and anxiety) in the European population, we used Mendelian randomization (MR) analysis, which provides definitive evidence for causal inference. Eligible single nucleotide polymorphisms were screened for dermatological and psychiatric disorders using a genome-wide association study database. We conducted bidirectional, 2-sample MR analysis using instrumental variables related to psoriasis, eczema, and urticaria as exposure factors, and bipolar disorder, schizophrenia, major depression, and anxiety as outcomes. Reverse MR analysis with bipolar disorder, schizophrenia, major depression, and anxiety as exposure and psoriasis, eczema, and urticaria as outcomes were also performed, and the causality was analyzed using inverse-variance weighting (IVW), MR-Egger, and weighted median methods. To thoroughly assess causality, sensitivity analyses were conducted using the IVW, MR-PRESSO, and MR-Egger methods. The results showed that bipolar disorder increased the incidence of psoriasis (odds ratio = 1.271, 95% confidence interval = 1.003-1.612, P = .047), heterogeneity test with Cochran Q test in the IVW showed P value > .05, (P = .302), the MR-Pleiotropy and MR-PRESSO (outlier methods) in the multiplicity test showed P value > .05, (P = .694; P = .441), and MR-Pleiotropy evidence showed no apparent intercept (intercept = -0.060; SE = 0.139; P = .694). Major depression increased the risk of eczema (odds ratio = 1.002, 95% confidence interval = 1.000-1.004, P = .024), heterogeneity test showed P value > .05, (P = .328), multiplicity detection showed P value > .05, (P = .572; P = .340), and MR-Pleiotropy evidence showed no apparent intercept (intercept = -0.099; SE = 0.162; P = .572). Sensitivity analyses of the above results were reliable, and no heterogeneity or multiplicity was found. This study demonstrated a statistically significant causality between bipolar disorder and psoriasis, major depression, and eczema in a European population, which could provide important information for physicians in the clinical management of common skin conditions.

Postpartum depression (PPD) is an increasingly prevalent but still poorly characterized disorder. Causal and modulating factors include hormones fluctuations, such as estrogen, progesterone, and allopregnolone, pathways imbalances, such as oxytocin and kynurenine, chronobiological factors, and brain imaging alterations. Treatment may differ from the traditional major depression management, while selective serotonin reuptake inhibitors such as sertraline are commonly used and suggested by guidelines, neurosteroids such as brexanolone and the more convenient zuranolone have been recently approved. Newer neurosteroids such as ganaxolone, valaxanolone, and lysaxanolone are currently under development, but also esketamine and psychedelics are promising potential treatments. Other somatic treatments including brain stimulation techniques and light therapy also showed benefit. PPD is therefore increasingly understood as, at least partially, independent from major depressive disorder. Specific and individualized treatments including pharmacological and non-pharmacological therapies are progressively being introduced in the routine clinical practice.

PURPOSE
Postpartum mood disorders affect many women following childbirth. Prescribing medication for depression and anxiety is one strategy for the effective treatment of postpartum mood disorders. Left untreated, mothers experiencing these disorders and their infants face increased risks of adverse health outcomes. Little is known about how diagnosis and treatment of postpartum mood disorders changed during COVID-19.
METHODS
We used a retrospective pooled cross-sectional design in a sample of privately-insured postpartum women in U.S. claims data from January 1, 2016 to December 31, 2020. We measured changes in diagnoses of anxiety and depression and changes in prescription fills and days supplied of classes of medications used to treat these conditions (antidepressants, benzodiazepines, and z-drugs). We used ordinary least squares (OLS) regression for each outcome variable during the pre-pandemic period and forecast expected outcomes the observation period. Forecasted and actual values of the outcomes were then compared.
RESULTS
Following the onset of the COVID-19 pandemic in March 2020, diagnoses of depression and anxiety were not significantly higher among privately insured postpartum women in the United States. The proportion of privately-insured postpartum women filling a benzodiazepine prescription increased by 15.2%.
CONCLUSIONS
We find diagnosis of postpartum mood disorders did not increase after the onset of the COVID-19 pandemic, however, fills of benzodiazepines increased among privately-insured postpartum women. Given prior evidence of increased depressive and anxiety symptoms among postpartum women during COVID-19, this suggests increased barriers to appropriate diagnoses and treatment for depression during this period.

Experiences of imagery-based treatment for anxiety in bipolar disorder: A qualitative study embedded within the image based emotion regulation feasibility randomised controlled trial.
OBJECTIVES
Intrusive mental imagery is associated with anxiety in bipolar disorder (BD) and presents a novel treatment target. Imagery-based treatments show promise in targeting anxiety and improving mood instability. This qualitative study explored experiences of receiving up to 12 sessions of a brief structured psychological intervention: Image-Based Emotion Regulation (IBER), which targets maladaptive mental imagery in the context of BD with an aim to modify the emotional impact of these images.
DESIGN
A qualitative study embedded within the Image Based Emotion Regulation (IBER) feasibility randomised controlled trial.
METHODS
Semi-structured interviews were conducted with 12 participants in the treatment arm of the trial who received IBER + treatment as usual. Data were analysed using thematic analysis.
RESULTS
Despite some initial scepticism about imagery-focused treatment, all participants expressed broadly positive accounts of treatment experiences. High levels of engagement with imagery modification techniques, beneficial use of techniques post treatment and improvements in anxiety management and agency were described by some. Three sub-groups were identified: those who reported a powerful transformative impact of treatment; those who embedded some new techniques into their daily lives, and those who felt they had techniques to use when needed. No participants reported overall negative experiences of the IBER treatment.
CONCLUSIONS
Findings from this study highlight the value for treatment recipients of modifying the underlying meanings associated with maladaptive imagery, and the personalised skills development to manage anxiety within bipolar disorders. Findings can inform treatment refinements and further trial-based evaluations.

INTRODUCTION
Less than three decades ago, depression was seen as a predominantly adult disorder as children were considered too developmentally immature to experience depressive disorders, and adolescent low mood was considered as part of 'normal' teenage mood swings. Major depressive disorder in children and adolescents is a serious psychiatric illness especially in paediatric surgical patients. This may be due to their altered metabolic rate and heighten metabolic response to trauma which has significant implications for the psychological development of the child, yet it remains under-recognized and undertreated. The well-being of the care givers is also not left out as the care givers are inundated with the task of sourcing and providing finance for hospital care., in addition to the stress of providing care for the patient. This may result in loss of man hour, sleeplessness, and physical exhaustion associated with caring for these ill children which can ultimately significantly increase the risk of them having depressive episode. The aim of this commentary is to highlight the fact that paediatric surgical patients are not exempt to having a major depressive disorder and the care givers should also be evaluated during hospital admission of their wards.
METHODOLOGY
This is a commentary on depressive disorders among Nigerian paediatric surgical patients. Related publications on children and adolescents presenting to hospital were searched using the domain - Depression in Nigerian adolescent, Paediatric surgery patients on PubMed, Google Scholar, and MEDLINE to appraise this review.
CONCLUSION
Mood disorders, especially depression in children and adolescents have been studied increasingly over the last two decades and surgical conditions worsen the outlook, culminating in increased knowledge about the presentation, and treatment. Despite this, it is still often missed or misdiagnosed because it sometimes presents with uncharacteristic symptoms. Prevalence of depressiion among paediatric surgical patient were found to be between 46-82% in this review among Nigerian patients.

Stimulants are the first-line pharmacological treatment for attention deficit hyperactivity disorder (ADHD). We present the unique case of a patient who developed a chewing compulsion when taking mixed amphetamine salts (MAS). A 32-year-old female patient with a past medical history of gastroesophageal reflux disease (GERD), gastroparesis, and migraines was seen for initial psychiatric assessment due to concerns for irritability. She was diagnosed with post-traumatic stress disorder (PTSD); generalized anxiety disorder; ADHD, inattentive type; and unspecified bipolar disorder. Lamotrigine was started and titrated to 25mg twice per day, with improved mood stability. MAS immediate-release (IR) was started at 2.5mg and titrated to 5mg daily for ADHD. She then experienced an uncontrollable urge to chew, finding relief when chewing on a child's teething necklace, which provided satisfaction and a reduction in anxiety. She denied jaw tightness or teeth grinding. The dose of MAS IR was reduced to 2.5mg daily with improvement in symptoms and later increased again to 5mg daily, which she was then able to tolerate. Stereotyped biting behaviors have been observed in rats with the use of amphetamines, and the onset of compulsive behavior has emerged in children with the use of dextroamphetamine. However, this is the first known case of compulsive chewing or biting movements reported in humans with MAS use. This case highlights the need to assess patients for adverse events, such as compulsive biting and chewing movements or other oral facial stereotypies, after commencement of stimulants, including MAS.

Review
Major depressive disorder (MDD) is a recurrent episodic mood disorder that represents the third leading cause of disability worldwide. In MDD, several factors can simultaneously contribute to its development, which complicates its diagnosis. According to practical guidelines, antidepressants are the first-line treatment for moderate to severe major depressive episodes. Traditional treatment strategies often follow a one-size-fits-all approach, resulting in suboptimal outcomes for many patients who fail to experience a response or recovery and develop the so-called "therapy-resistant depression". The high biological and clinical inter-variability within patients and the lack of robust biomarkers hinder the finding of specific therapeutic targets, contributing to the high treatment failure rates. In this frame, precision medicine, a paradigm that tailors medical interventions to individual characteristics, would help allocate the most adequate and effective treatment for each patient while minimizing its side effects. In particular, multi-omic studies may unveil the intricate interplays between genetic predispositions and exposure to environmental factors through the study of epigenomics, transcriptomics, proteomics, metabolomics, gut microbiomics, and immunomics. The integration of the flow of multi-omic information into molecular pathways may produce better outcomes than the current psychopharmacological approach, which targets singular molecular factors mainly related to the monoamine systems, disregarding the complex network of our organism. The concept of system biomedicine involves the integration and analysis of enormous datasets generated with different technologies, creating a "patient fingerprint", which defines the underlying biological mechanisms of every patient. This review, centered on precision medicine, explores the integration of multi-omic approaches as clinical tools for prediction in MDD at a single-patient level. It investigates how combining the existing technologies used for diagnostic, stratification, prognostic, and treatment-response biomarkers discovery with artificial intelligence can improve the assessment and treatment of MDD.

BACKGROUND
Pulmonary embolism (PE) is a severe and life-threatening complication of venous thromboembolism. However, there is a lack of systematic studies on differences between female and male PE patients. This paper aimed to compare the sex-specific differences in clinical characteristics and laboratory indicators in psychotic patients with PE.
METHODS
This retrospective study enrolled psychiatric patients with PE from June 2018 to June 2022 at Shenzhen Kangning Hospital (Shenzhen Mental Health Center). Demographic characteristics, factors associated with PE, and laboratory indices were collected to assess sex-specific differences.
RESULTS
Of the 168 patients, 87 (51.8%) were female and 81 (48.2%) were male, with a mean age of 58 years for females and 46 years for male patients. The male group had higher ratio of hyperprolactinemia, more patients using antipsychotic medications, higher D-dimer levels at PE onset, greater D-dimer difference, and a higher rate of D-dimer elevation than the female group (p < 0.05). Female patients were significantly older, exhibited a higher prevalence of diabetes, and had a greater number of patients taking antidepressants and hypnotics/sedatives than male patients (p < 0.05). Schizophrenia spectrum disorders were more prevalent in male patients, while female patients had a higher incidence of mood disorders (p < 0.05). Among patients aged < 45 years, the male group had higher D-dimer levels at PE onset and greater D-dimer difference (p < 0.05). Among all 112 patients aged ≥ 45 years, male patients were more likely than female patients to have respiratory tract infections, higher D-dimer levels at PE onset, greater D-dimer difference, and a higher rate of D-dimer elevation (p < 0.05). The multiple linear regression analysis indicated that hyperprolactinemia and the use of first-generation antipsychotics (FGAs) were associated with D-dimer levels at PE onset in male patients, while the time of PE onset and protective restraints were associated with D-dimer levels at PE onset in female patients (p < 0.05).
CONCLUSION
PE-associated clinical features differ between male and female patients. These differences may imply that the processes and mechanisms of PE onset are sex specific. Male patients are more likely to have respiratory tract infections and higher D-dimer levels at PE onset than female patients. The use of FGAs may be associated with increased D-dimer in male psychiatric patients, while protective restraints may be associated with increased D-dimer in female psychiatric patients.

Repetitive transcranial magnetic stimulation (rTMS) is an established non-invasive brain stimulation treatment for major depressive disorder, but there is marked inter-individual variability in response. Using latent class growth analysis with session-by-session patient global impression ratings from the recently completed BRIGhTMIND trial, we identified five distinct classes of improvement trajectory during a 20-session treatment course. This included a substantial class of patients noticing delayed onset of improvement. Contrary to prior expectations, members of a class characterised by early and continued improvement showed greatest inter-session variability in stimulated location. By relating target locations and inter-session variability to a well-studied atlas, we estimated an average of 3.0 brain networks were stimulated across the treatment course in this group, compared to 1.1 in a group that reported symptom worsening (p < 0.001, d = 0.893). If confirmed, this would suggest that deliberate targeting of multiple brain networks could be beneficial to rTMS outcomes.
